Install HWIC on Cisco router 2811

Hello all,
I installed the HWIC CDMA on router 2800. I have read the document from Cisco website and I made a proposal. However, I don't know how it works.
Could you please take a look and give me your opinion? I hope I will hear something from you
Thank you

HWIC is installed on the slot 2 of the router 2800. We have wireless service with Verizon.

It looks like there are a few things missing for full connectivity like encapsulation and authentication.  What do you get in the logs when you turn on chat script debugging and ppp authentication debugging?

This is just my proposal. I had this from the Cisco article. Could you please show me what I have missed.
Thank you

I tend to run connections like this through "Dialer" interfaces rather than on the hardware itself, but the principle is similar.  Here's the relevant configuration from a working installation that I have.  Replace the ########## with the phone number assigned to your EV-DO HWIC's Verizon account.  You'll want to adjust routing and dialler permit lists accordingly.

interface Cellular2/0/0
 no ip address
 encapsulation ppp
 dialer in-band
 dialer pool-member 1
interface Dialer1
 ip address negotiated
 encapsulation ppp
 dialer pool 1
 dialer idle-timeout 0
 dialer string "#777"
 ppp authentication chap pap callin
 ppp chap hostname
 ppp chap password 0 ##########
 ppp pap sent-username password 0 ##########
 no cdp enable
ip route Dialer1
dialer-list 1 protocol ip permit
